Title: Memory control circuit
Inventor: TAKEHANA MASASHI
IPC: G11C11/41
Filed: 1989-04-25
Abstract: PURPOSE:To enable access to be performed from a CPU at a port side on which priority is desired to attach by controlling a standby signal outputted to a side on which the priority of the access is desired to attach out of a first CPU side and second CPU side at an inactive state. CONSTITUTION:CPUs are arranged at both sides of a memory part 3 composed of parallelly connected dual port RAMs 1 and 2, and the readout and write of data can be performed independently at the port 1A and 2A sides and the port 1B and 2B sides. When the priority is attached on the port 1A and 2A sides, and when signals busy(BS) are outputted from the RAM 1 to the port 1A side and from the RAM 2 to the port 2B side, respectively, both the signals BS at the port 1A and 2A sides are set at the inactive states, which permits the access from the port 1A and 2A sides. Also, even when the signals BS are outputted from the RAM 1 to the port 1B side and from the RAM 2 to the port 2A side, respectively, the signals BS at the port 1A and 2A sides are set at the inactive states, which permits the access with priority similarly.

Abstract: PURPOSE:To make channel selecting operation light by smoothing the transverse motion of two transverse motion plates. CONSTITUTION:When channel selection member A1 in a suppressed state is pushed while memory member 4 is pressed against crossarm 1 by determent piece 5, one working part 3a strikes slanting ege 9a opposing to it and this striking action moves one transverse motion plate 8a to the left while it is being supported by one inflection link piece 12a and one link piece 19a and also moves slide plate 16 as shown by the arrow. According to his movement, the other inflection link piece 12b also rotated by projecting shaft 17, and consequently, the other transverse motion plate 8b moves in the opposite direction to transverse motion plate 8a, so that slanting edge 9b of window hole 10b provided to it will strike the other working part 3b opposing to it. When working parts 3a and 3b strike slanting edges 9a and 9b respectively, channel selection member A1 stops advancing and variable tuning element 14 is varied as much as the extent of moving displacement of transverse motion plates 8a and 8b equivalent to the rotation angle of memory member 4.

Title: High speed calculation system for distance between pictures
Inventor: YOSHITANI KIYOSUMI
IPC: G06T7/00
Filed: 1993-04-07
Abstract: PURPOSE:To compress a retrieval time for retrieving similar pictures by utilizing information of run length of a white picture and a black picture obtained from a run length code so as to calculate a distance between pictures without reproduction of the pictures. CONSTITUTION:A run length of a white picture and a black picture is obtained from a run length code stored in a picture database. Similarly a run length of a white pixel and a black pixel is obtained from a run length code of the picture to be retrieved. Then in the case of similar picture retrieval in which the picture itself is used for a retrieval key, the reproduced retrieval picture and the picture to be retrieved are overlapped and a distance between pictures is defined by the total number of numatched pixels (pairs of white and black level pixels) and the picture to be retrieved is outputted as a similar picture in which the distance is minimized. Then the distance is directly calculated without reproducing the retrieval picture and the picture to be retrieved. Thus, the distance between two binary pictures is obtained by the calculation with respect to series of run length.

Title: Current correcting circuit
Inventor: TAKAHASHI KYOICHI
IPC: H03F3/45
Filed: 1986-05-12
Abstract: PURPOSE:To stabilize the amplification factor of an amplifier circuit receiving a constant current by correcting the variation of a current amplification factor of a PNP transistor (TR) for constant current supply by another PNP TR formed separately at the same time. CONSTITUTION:A luminance signal Vin inputted to a terminal 1 of an AGC circuit IC for VTR is amplified by a preamplifier 3 and an amplifier 2 to drive an output TR Q6 and to output an AGC signal V0 to a terminal 3. A PNP TR Q11 supplies a constant current to a TR Q3 of the amplifier 2. A TR Q12 of a current correction circuit 1 is made by the same process as that of the TR Q11 and a constant voltage V1 is impressed from a constant voltage circuit 4 similarly as the TR Q11. Even if the current fed to the TR Q3 is fluctuated due to the variation of the current amplification factor caused by the manufacture process of the TR Q11, since the TR Q12 corrects the constant current supplied to the amplifier 2 via current mirror circuit comprising the TRs Q13, Q14, a stable AGC output signal is obtained.

Abstract: PURPOSE:To prevent overcurrent from flowing through a switching element, etc., for on/off-controlling plasma discharge at the time of plasma discharge even when the number of series circuits of the switching elements and plasma electrodes are increased. CONSTITUTION:Anode electrodes 9A1-9An are connected in common, and are connected to a positive polarity side of a power source 31. Cathode electrodes 9K1-9Kn-1 are connected to one ends of switches SW1-SWn-1 respectively. The other ends of respective switches SW1-SWn-1 are divided into x blocks, and are connected in common for every block, and a common connection point is connected to the negative polarity side of the power source 31 through diodes D1-Dx and a constant current source 32. By successively turning on the switches SW1-SWn-1, plasma discharge is generated successively on a pair of discharge channels 12 respectively placing on respective both sides of the cathode electrodes 9K1-9Kn-1. Equivalent capacity connected to a series circuit of a switch, cathode electrode and anode electrode in parallel is reduced, and a discharge current flowing from the equivalent capacity at the time of plasma discharge is reduced.

Title: Cascade type current division circuit
Inventor: OOHATA MICHINOBU
IPC: H03M1/74
Filed: 1978-08-31
Abstract: PURPOSE: To reduce the trouble for adjustment of the current division circuit by securing the cascade type current division transistor or the transistor pair.  
     CONSTITUTION: The properties of each transistor (such as the VBE pair IC properties, β properties, emitter area, etc.) are matched with every pair. And current division transistor pairs (1 -1 , 1 -2 ), (2 -1 , 2 -2 ), (3 -1 , 3 -2 )... featuring the optional current division ratio determined by the emitter area ratio are given the cascade connection. The basement part of the cascade connection is connected to constant current source 14, and at the same time the bias voltage is applied to each transistor pair via common base bias current sources 5∼8 corresponding to each transistor pair. Thus the output current ratio of each of output terminals 9∼12 and 13 features IS/2:IS/4:IS/8:IS/16:IS/16 in case the constant current flowing to source 14 is defined as IS. Then the weighting is given to the binary 4 bits to make transistor pairs conduct, and as a result the current division becomes possible without giving matching to all transistor properties.
